On May 20, 1969, while Apollo 10 was on its way to the Moon, the Saturn V that carried Apollo 11 on its historic journey took the first steps toward its ultimate destination. Apollo 11 astronauts Commander Neil A. Armstrong, Lunar Module Pilot (LMP) Edwin E. “Buzz” Aldrin, and Command Module Pilot (CMP) Michael Collins were on hand to watch their rocket make its slow trek from the Vehicle Assembly Building (VAB) to Launch Pad 39A at Kennedy Space Center. They were busy preparing for the mission by practicing for the first moonwalk and training for splashdown and recovery, including wearing Biological Isolation Garments to protect Earth from possible lunar microbes. The Mobile Quarantine Facility that housed them from splashdown until arrival at the Lunar Receiving Lab was delivered to the Manned Spacecraft Center, now the Johnson Space Center in Houston. The Lunar Module (LM) completed tests to certify it for the loads it would encounter during the Moon landing.

On May 14, Armstrong, Aldrin, and Collins held a press conference at MSC to discuss their upcoming mission. They each provided explanations about their specific roles in the mission and answered numerous questions from the assembled reporters.

During the week of May 5, Apollo 11 prime and backup crewmembers trained for the first lunar surface Extravehicular Activity (EVA), or spacewalk. The training sessions with the astronauts wearing pressure suits and under near-vacuum conditions took place inside Chamber B of MSC’s Space Environment Simulation Facility (SESL). These training sessions followed previous ones in Chamber B that were conducted at sea level. During the training, astronauts practiced operations they would conduct on the Moon, including extracting experiment packages from the LM and setting them up on the surface.

To safeguard against the remote possibility that astronauts returning from the Moon might harbor potentially harmful microorganisms, NASA put in a place a stringent postflight quarantine program for the crewmembers, their spacecraft, and the lunar samples they brought back. The Lunar Receiving Laboratory (LRL) at MSC was the facility where the postflight quarantine took place, but additional measures were required for the time period between splashdown and the crew’s arrival at the LRL. The first of these measures involved the crewmembers donning Biological Isolation Garments (BIG) prior to exiting the spacecraft after splashdown. Since the crew didn’t carry the BIGs with them to the Moon and back, one of the recovery personnel, also clad in a BIG, opened the hatch to the capsule after splashdown and handed the suits to the astronauts inside, who donned them before exiting onto life rafts. Lieutenant Clancy Hatleberg of the US Navy’s Underwater Demolition Team-11 (UDT-11) served as the biological decontamination swimmer for Apollo 11. In addition to providing the crewmembers with the BIGs he also sprayed the capsule, the astronauts, and himself with a disinfectant before they were brought aboard the prime recovery ship. On May 24, the Apollo 11 astronauts and Lt. Hatleberg rehearsed these procedures in the Gulf of Mexico near Galveston, Texas, using a boilerplate Apollo Command Module (CM) and supported by the Motorized Vessel (MV) Retriever.

Another component of the postflight quarantine program was the Mobile Quarantine Facility (MQF) that housed the returning astronauts along with a flight surgeon and an engineer from their arrival aboard the prime recovery ship to their return to the LRL. The MQF designated for Apollo 11, the third in a series of four units delivered to NASA from the manufacturer Airstream Company of Jackson Center, Ohio, arrived at MSC on May 12. Airstream built the MQFs under contract to Melpar, Inc., of Falls Church, Virginia. NASA engineers had put the first MQF through extensive testing including onboard the USS Guadalcanal, the prime recovery ship for Apollo 9. Lessons learned from those tests were incorporated into the later units. The MQF, a highly modified 35-foot Airstream trailer, contained a lounge, a galley with microwave oven, sleeping quarters and a bathroom, was powered internally by a diesel generator and batteries, and could interface with ship and aircraft power systems. It could support six people for up to 10 days. The MQF would be offloaded from the prime recovery ship, flown aboard a transport aircraft back to Houston, and finally trucked to the LRL.

To certify the LM and its systems for the loads it would encounter during a lunar landing, on May 7 engineers at MSC completed the fifth and final drop test with the flight-like LM-2 in the Vibration and Acoustics Test Facility (VATF). The first four tests conducted in March and April established the functioning of all LM systems after the impacts of a lunar landing. This final test qualified the LM’s pyrotechnics. The series of tests completed the certification of the LM for the first lunar landing.
